Comment:

 We started parsing descriptors with multiple threads for #31204 which we
 deployed 2 months ago. In that context we discovered and fixed #32194. We
 have been parsing many, many descriptors in parallel since then. We didn't
 find anything else. I'd say it's safe to assume that there are either no
 more issues with thread-safety or that they're really hard to trigger. I
 also took a quick look at the metrics-lib code to see if there are similar
 bugs like #32194, but didn't find anything. Investigation concluded.
 Closing.
